I thought it was a little silly.
Lm380 audio amplifier circuit.
The working of the circuit is very straight forward as all the work is done by the lm386 ic itself.
But after prototyping with this audio amp i don t think i ll ever go back to the lm386.
It s run 9 voltage to 15 voltage.
Now that you ve seen the bare minimum of what it takes to make an audio amplifier with the lm386 lets build a higher fidelity version with an adjustable gain control.
In order to hold system cost to a minimum gain is internally fixed at 34 db.
In the car also can use this circuit diagram.
The circuit shown in figure 1 is a very simple audio power amplifier.
A great sounding lm386 audio amplifier.
10v 22v the lm380 is a power audio amplifier for consumer.
The lm380n audio amp.
Normally we use 12 voltage for this amplifier circuit diagram.
Most of the component values in this circuit aren t critical.
A simple but efficient audio amplifier is designed using lm386 audio amplifier ic.
Mini amplifier circuit diagram using lm380.
Which use outside equipment adds least.
The output is short circuit proof with internal thermal limiting.
Mini audio amplifier circuit.
This is mini size power amplifier 2 watt otl that use ic lm380.
The simplicity of this circuit is made possible by the lm380 s minimal requirements for external components since it is already internally equipped with the necessary biasing compensation and gain circuits.
Emitter follower pnp emitter follower.
The circuit can be connected in four stages which include the following.
But this sound is so clear and melody.
This paper describes the circuit operation of the lm380 its power handling capability methods of volume and tone con trol distortion and various application circuits such as a bridge amplifier a power supply splitter and a high input impedance audio amplifier.
This is a simple audio amplifier using lm380 ic.
I was a little intimidated by this ic the first time i looked at the datasheet because of all the ground connections.
The main component of this circuit is the lm380 audio amplifier.
Circuit description figure 1shows a simplified circuit schematic of the lm380.
When the system is powered on and proper audio input is given at the input the lm386 amplifier the input signal by a factor of 200 and drives the output speaker.
Lm380 1features description wide supply voltage range.
The lm380 is a power audio amplifier for consumer applica tions.
If you need only vocal then you can use this circuit diagram.
A unique input stage allows ground referenced input signals.
The c6 can choose get many the value since 47uf to at 470uf which have a voice good bass.
Be base readymade circuit for side sound work and the communication.
